Sleep Deprivation

Not getting enough sleep, doesn’t just make you feel bad, it can also damage your health. The US National Sleep Foundation says “In the past century, we have reduced our average time in sleep. Though our society has changed, our brains and bodies have not. Sleep deprivation is affecting us all and we are paying the price.” And the price we pay is not only that of looking old before our time, but also of increased risk of chronic medical conditions.

“What many people do not realize is that a lack of sleep—especially on a regular basis—is associated with long-term health consequences, including chronic medical conditions like diabetes, high blood pressure, and heart disease, and that these conditions may lead to a shortened life expectancy” (Harvard Medical School).

Inadequate Sleep and Weight Gain

Research has also identified a relationship between inadequate sleep and weight gain. Studies have shown that individuals who regularly get less than six hours sleep are much more likely to have a higher than average body mass index (BMI) while people who sleep eight hours have the lowest BMI.

Lack of Sleep and Increase in Stress Hormone

An adequate amount of sleep is also necessary for good mental functioning. For example, studies have shown that inadequate sleep leads to an increase in the production of cortisol – your body’s stress hormone.

How many hours of sleep are needed for good health? The recommended amount of sleep for adults is 7-8 hours (Mayo Clinic).
